In my improved machinethe elevator is put up by aweight, spring, or other means which through intermediate j connecting mechanism operates when the elevatory is free, to lput itf-up, and my invention consi/stsin providing means for effecting an auto-i matic break at some point in the intermediate connecting mechanism, thereby allowing the elevator to fall by gravity, and in means for automatically and periodically restoring the connection.

-'I will now proceed to describe one specific embodiment of my improvement, reference being had Vto the accompanying drawing in Figure 1 is a perspective view of so Inuch of said linotype machine as is lnecessaryto illustrate the manner in which* my improved weight to put up t e elevator; Fig. 2 is a plan view of the mechanism for makingv andv breaking the connection between the weight and the elevator lever: Fig. 3 is a vertical longitudinal sectional view on line X-QX, Fig. 2, the lconnecting latch and spring being omitted, `and Fig. 4 is a detail perspecthe automatic latch and its support.y f

Same letters of reference refer to like parts.

.In said drawings A represents the elevator, B the vertical guides between which it moves, C portions of the columnD the line delivery carriage shaft, E- the line delivery carriage lever, li the lever for raising the elevator rigid on shaft H and G a link connect-` ing the elevator and lever F. These parts are `substantially the same and operate in the same way as in said linot pe machine.

ing providedlwith an upright'bar 2 substantially parallel with link G. y.Link G is provided on one side with an oset3 and on the other side withan offset 5. Pivotally attached-to bar 2 is a latch 4 adapted to engage offset 3 when the elevator is down and to be manuallyl disengaged. Pivotally attached to a plate 6 securedto. guides B is a latch 7 adapted to engage offset 5 when the elevator is down and to be automatically disengaged by the return of the line delivery carriage lever. Theselatches `are held inI 'engagement with their respective' offsets by springs 8 and 9 respectively and both must be disengaged before the elevator can be sent up.

Secured to shaft H is a lever arm l0 which may be rigid therewith or which may be loosely mounted thereon and provided with a lug 11 projecting into the path of the leverA F in whichcase lever F and with it theelevator is free to be raised independently of arm f 10. Connecting with the assembling elevator through said lever arm 10, and ,operated by weight 20 and lug 31 bothbelow men# tioned, is a. trip-hook mechanism which wel now proceed to describe.l

Mounted upon bracket 1- is a two y art slidi pulley 19 is a Weight 20 which weight should be suilicient to raise the elevator when free to go up and when the parts 12 and 14 are connected as 'hereinafter described. The

partsz12 and 14 are secured on the bracket rand held in alinement/ therewith by meansl of screws 33 on the parts ofthe slidin plate and projecting through slots 34 1n the bracket, as shown in Fig. 3. y

The parts 12 and 14 of the sliding plate are adaptedi to be connected and `,disconnected as hereinafter described, for the purpose, when connected and the elevator is free, of putting up" the elevator7 byv means of f the weight, and, when disconncted, of permitting the elevator to return down,by gravity. For the purpose of .detachably connectiu the two parts 12 and 14 a latch 21 is pivota ly connected to one of the parts of the sliding plate and a keeper 22 is rigidly secured to the other part of `the sliding plate. fl he latch 21 is adapted to be held yieldingly in engagement with its keeper by means of a spring 23. To `disengage the latch a knocker 24 is pivotally secured to abracket 25 which for convenience is secured to bracket 1. The lower extremity of the knocker may be provided with an adjusting screw h26 which is adapted, when the knoeker is turned on its pivot, to strike the arm of the latch and disengage it from its keeper. The pivoted knocker is actuated by means of link 29 pivotally attached to it and to the end of the line delivery carriage shaft by means of which it is operated in time with the movement of said shaft, the rocking movement of the line delivery carriage shaft raising the link 29 and actuating the knocker to throw the latch out of engagement. This is adjusted by means oi screw 26 to take place just when the line of matrices has passed out of the elevator, the disengaging ot the latch allowing the separa tion ,of the two parts 12 and 14 of the plate and thereupon the elevator raising mechanism being free from the influence of the weight, the elevator returns down by gravity until one or both of the latches which hold the elevator down engage their respective offsets, the part 12 of the sliding plate being y carried outwardly to the `farthest extent.

To restore the connection'between the two parts 12 and 14, the line delivery carriage shaft which has a rocking motion is provided with a` lun* 31 which, as the line delivery carriage shalt is rotated, engages arm 30 of the bel crank lever and raises the weight pushing the part 14 forward until latch 21 comes into engagement with keeper 22 again connecting parts 12 and 14, completing the cycle o'l movement and putting the elevator in readiness to be sent up, Whenever it is released.

` To counterbalance the weiglit of and to lessen the shock due to the unobstructed fall of the elevator, ll employ a spring 32 connecting lever arm 10 and some stationary member as bracket 2.

The operation is as follows. Assume the parts to be in the ,position shown in Fig. 1 With the elevator down held d own by the hand-operated latch, the automatic latch being thrown out by the line delivery carriage lever, and the weight and its connections tending to raise the elevator. The hand-operated latch is then disengaged and the weight, through its connections immediatelyv sends up the elevator. The line delivery carriage shaft turning to the left'midway its movement causes -through the knoeker and intermediate mechanism the disconnection of parts 12 and 14 allowing the elevator to return to its down position by gravity. As the line delivery carriage shaft continues its course lug 31 en ages arm` 30, raises the Weight and again e ects the connection of parts 12 and 14. The line delivery carriage shatt has a rocking motion through an angle of about forty-five degrees.
